MICHAEL REILLY, OE BROOKLYN, NEIV YORK.

FIRE-KINDLER.

SPECIFICATION forming part of Letters Patent No. 400,252, dated March26, 1889.

Application iiled September 10, 1887. Serial No. 249,296. (No model.) A

To all whom it may concern.-

Bc it known that I, MICHAEL REILLY, of Brooklyn, iii the county of Kingsand State of New York, have invented a new and useful Improvement inFire-Kindlers and Fuel- Cartridges, and in the Method of Making theSame, of which the following is a specification.

Bone -black or animal charcoal is very largely used in filteringhydrocarbon oils, and after such use of the bone-black there necessarilyremains therein from twenty to thirty per cent. of oil., of which thelarger part is difficult of abstraction.

The important object of my invention is to utilize this spent bone-blackfor fire-kindlers and fuel-cartridges, for which purpose it is veryvaluable on account of the oil remaining in it. If the oil remaining inthe bone-black shall not be enough to adapt it for the purpose, theiire-kindlers or fuel-cartridges made therefrom may be made to take upmore oil, as bone-black or animal charcoal, owing toits porouscharacter, is one of the more ready absorbents.

I will describe in detaila fire-kindler embodyin g my improvement, andthen point out the novel features in a claini.

In the accompanying drawings I have sought l to show as clearly aspossible both a smalli sized re-kindler and a larger fuel-cartridge iembodying` my invention.

Figure l represents a lire-kindler, and Fig. i 2 a fuel-cartridge.

A in Fig. l designates the fire kindlei, which may be iliade in cubical,cylindrical, or other shape, and may be, say, four to six 1 ounces inweight; and B in Fig. 2 designates the fuel-cartridge, which may be acube, cylinder, or other shape, and which iiiay weigh several pounds.

As above stated, there remains in the boneblack which has been used forfiltering oil a i considerable portion of oil, most of which isdifficult of recovery, and it is of comparatively little value for thepurposes to which it has heretofore been applied. This bone-black, xeither with only the oilwhich it naturally contains after being used asa filtering inedium, or with more oil which it has been made to absorb,is of great value for iire-kindlers or fuel-cartridges, owing to itsgreat porosity Q and its resistance to heat. To put it in proper shapefor market, I preferably combine with i the spent bone-black asufficient proportion i of clay, plaster-of-paris, or other bindingniaterial, and after adding sufficient water to make a soft paste Iforni or cast this past-e iii suitable molds which may be made of tin,and which are of sizes to produce the desired sizes of tire-kindlersorfuel-cartridges. Aftei' the bodies, blocks, orbricks are removed fromthe molds they are dried at a heat sufficient to evaporate the water,but not the oil. As a cement or binding material, I now deem itdesirable to employ with plaster-of-paris a little fire-clay or asbestuscement, which enables the cartridge to better resist the action of thefire; but it is believed that such fireclay or asbestus cement will notbe needed in the smaller-sized fire-kindlers, which are in tended to beused but once and left in the fire.

The fuel-cartridges which are intended to be reused should be made withmore care, and sufficient fire or pipe clay or asbestus cement should beadded during their manufacture to enable them to withstand the heatfor along time and to be used repeatedly. The proportions of bone-black andcement or binding material added thereto may be widelyvaried, it beingmy intention to only employ sufficient ceinent or binding material tohold the bone-black in a body and prevent its disintegration. I now deemit desirable to employ three parts of spent bone-black and one part ofplaster-of-paris. After the Iire-kindlers and cartridges aremanufactured sufficient oil to bring tliein up to the point ofsaturation may be added. The small-sized iire-kindlers, which areintended to be but once used, are allowed to remain in the fire which,they have ignited and are thrown away with the ashes; but if thecartridges are made to be repeatedly used they are allowed, after theoil is once burned out of tlieiii, to rcabsorb sufficient oil to renderthemv capable of effective reuse, and in such case the cartridge willform, as it were, a wick from which the oil is consumed.

W hat I claini as my invention, and desire to secure by Letters Patent,is-

As a new article of manufacture, a firekindler composed of spentbone-black satiirated with oil and a binding `material, the whole beingformed into a block or brick, substantially as specified.
